APPLICATION OF THE STANDARDIZED PRECIPITATION INDEX FOR THE ASSESSMENT AND FORECAST OF ATMOSPHERIC DROUGHTS IN ALTAI KRAI

The research objective is to identify and analyze the possibility of using Standardized Precipitation Index (SPI) in Altai Krai for agroclimatic meteorological research, including forecasting climate change predicting yield various crops. An assessment atmospheric droughts within conditions was performed a method relatively new national agrometeorology. At moment, Russian Federation CIS countries, G. T. Selyaninov Hydrothermic Factor (HF) mainly used assessing droughts, which makes it possible assess territory water availability by ratio period characteristics with temperature above 10°С. authors have compiled SPI calculator Microsoft Excel software environment. paper presents graphs moisturization course active growing season 31 stations Krai, frequency arid events calculated compiling precipitation model 1964–2020. does not provide formulas described detail literature sources. results can be planning activities sphere agriculture, developing an economic strategy region, relation adaptation change. Areas are highlighted that priority-oriented taking measures prevent adverse consequences General tendencies changes agrometeorological indicators been found those areas where they greatest ones. A comparison made work regarding other entities near abroad, wherein analyzed.
